    This is a Ford Performance by Borla Sport Axle-Back Exhaust with chrome tips for the 2015 and newer S-550 EcoBoost Mustang. This axle-back is gonna be a good option for you if you're looking for a high-quality axle-back that gives you a throaty exhaust tone and you don't mind paying for quality. The axle-back features straight-through sport mufflers, and this setup is gonna give you a sound that isn't replicated by the other axle-backs for the EcoBoost that are out there either. As you guys already heard from the sound clips, the install for this is easy, it should take about two hours to get this all done, and it's a two out of three wrenches on the difficulty meter since there is some cutting involved, but we'll get more into that later. The main component of an axle-back is gonna be the mufflers, and in this case, we're looking at a set of straight-through sport mufflers. So with an axle-back you're still gonna have your stock mid-pipe, and that's all gonna lead down to the sport mufflers which are known for a loud and throaty exhaust note which you guys heard earlier in the sound clips. Keeping the stock mid-pipe does mean that you aren't gonna be opening up as much as possible as far as exhaust flow, but the combination of the sport mufflers and even the stock resonator mid-pipe creates a deeper than stock tone that isn't too loud and that also doesn't have any drone at highway speeds. Ford Performance describes the sound of this axle-back as loud, aggressive, and throaty, and I can't say that I disagree with that description. The sport mufflers give more of a raw sound when you compare to other options that focuses more on a tuned sound. And there is some popping on decel with this axle-back. I wouldn't say that it's too raspy either, but it gives more of that turbo four-cylinder sound. One thing I did notice, however, is that this system is loud and you don't get as much turbo noise here as I've heard with some other options that are out there. You can hear some spooling in there, but that's it. So if the turbo noise is something that you're really after, then there are some other options on the site that really open a lot of that turbo noise. This system does give more of what I consider a smoother sound when compared to other axle-backs, but it isn't very deep. Like I said, it has more of a loud and throaty note than a deep note or even a raspy note. And you have to keep in mind that this is a four-cylinder turbo car. It's not gonna sound like a V8. So if you're looking for more of that clean, deep type of sound, there are some other options that might be better than this one right here. Overall, while this system is loud, I wouldn't say that it's the loudest out there. It's gonna be on the louder side of the scale for the EcoBoost Mustang, and so I'm gonna give it a three out of five on the loudness scale. There are some louder systems out there if that's what you're looking for, but there are some quieter ones as well. It's really all gonna depend on what you're looking for, and luckily there are quite a few options out there. When it comes to materials and construction, this system right here has 4-inch chrome stainless steel tips and the Ford Performance logo is embossed on the tips so you won't be losing anything styling-wise. And as usual, stainless steel is always a great option for the cars that see all different types of road conditions since it's gonna offer the best corrosion resistance. And unlike some of the other EcoBoost axle-back options out there, this system actually bumps up the size. You'd be going from a two and a quarter inch system to a two and a half inch system and you're also looking at a full stainless steel manual-bent axle-back. As far as price goes, you can expect to spend just under $800 for this axle-back. This is on the more expensive side of things but you have to consider that Ford Performance is a high-end offering with high quality. So if that's something that you're concerned with, you're shopping in the right place. That means that you do have a ton of other options out there if this axle-back really doesn't suit you. So make sure that you check out the site if you aren't sure. You're gonna be looking at the typical cut and clamp design with the install for this axle-back since you need to cut all S-550 axle-backs. I'm gonna call this a two out of three wrenches on the difficulty meter, but just because of the cutting that's involved. Nothing difficult but I just recommend some eye protection and a fresh blade to make the cutting easier. Overall, you're looking at about two hours to get this all done. A lift would certainly make things easier for you here, but the job can be done on jack stands as well if you don't have access to one. Cutting the factory axle-back isn't hard, just be sure to measure twice and plant a mark where you will be cutting so you don't make a mistake. You can mark the axle-back with painter's tape if you want and then use a Sawzall to cut the stock axle-back out. It'll probably be easiest to leave the hangers on the axle-back and just unbolt them from the car. You can transfer them over to the new axle-back. Your new axle-back will come with new clamps for you, so you don't have to worry about that. When you go to install your new setup, it'll probably be easiest to leave everything loose until you have it all lined up and then tighten it down. That's gonna wrap things up for the Ford Performance by Borla Sport Axle-Back Exhaust with chrome tips for the 2015 and newer EcoBoost Mustang. You can check it out more online right here at "

        Is the part number stamped anywhere on these mufflers. I have a pair but not sure what part number the really are.

        • The part number would more than likely be on the packaging and not the item itself.

        Will this fit on a V6. If the answer is no, can you specify no about, the Length? Height? Piping? Hangers? Thank you

        • This will not fit on a V6 model as we have only confirmed fitment on the 15-19 Ecoboost models without active exhaust.

        Will these fit on a 2018 Mustang Ecoboost for sure? I called FRPP and they said they would NOT. Thanks

            Safe Bet

            Very easy to install. Helps to jack up the back end a few inches. Two quick cuts with a sawzall. Whole thing done in 15 to 20 minutes. Perhaps not as aggressive sounding as I would have liked but that's probably because I'd rather it sounded like a V8 or even a V6. I plan on adding a Y pipe and maybe a down-pipe eventually so maybe the combo will get me closer to the sound that I want. On the other hand, some of the more aggressive axle/cat back systems get very crackly sounding (not good in my opinion) and this one does not. It does produce a good, consistent sound.

            Waaaaay better sound...

            Attempting to get a better sound and deeper tone to my 2015 Ecoboost Mustang, I purchased the Flowmaster resonator delete Y-pipe and the Ford Racing mufflers. I looked at the full cat-back Ford Racing kit, but going this route saved about $400. The install went pretty well, with no major issues. I did notice that the Y-pipe to exhaust pipe connection did not hold my mufflers in place and they had a tendency to roll, but a quick trip to a local muffler shop fixed that. They tack-welded it at no cost. The sound is remarkably better and it definitely turns heads. It gives a waaaaay deeper tone and sporty sound. I love it!
